The plunge in stock prices means it’s time to earn the equity risk premium. Here’s a reminder about this important fundamental financial concept.
A rubric of modern portfolio theory taught at colleges and universities holds that investors get paid extra return for taking risk. The risk premium is the amount you get paid for owning a risky asset.
Over the 21 years and 11 months ended in November 30, 2018, the risk-free 90-day U.S Treasury Bill averaged an annual return of 2.1%, compared to a 7.2% annualized return on the S&P 500 stock index.
This period of nearly 22 years encompasses two full economic and bear market cycles — the tech-bubble bursting in 1999 and the global financial crisis of 2008 — so it is a fair period to examine in illustrating the equity risk premium.
The difference between the 7.2% average annual return on the S&P 500 index and the 2.1% return on a risk-free T-Bill is 5.1%. The extra return annually averaged on equity invested in America’s 500 largest publicly-held companies in the 21-year, 11-month period ended November 30, 2018 — is the equity risk premium, 5.1%.
In the context of the equity risk premium, the recent plunge in stock prices has been no huge surprise. The plunge followed a spectacular bull market run — nine consecutive calendar years of positive returns and a 10.8% return through the first three quarters of 2018.
Times of painful stock market losses are when investors actually earn the equity risk premium — and that’s an important financial fundamental to remember in times like these.
